The 635th Aircraft Control and Warning Squadron (AC&W) was a United States Air Force unit activated during the early Cold War period. Established in 1950, the squadron was tasked with operating radar equipment and providing air surveillance, early warning, and ground-controlled interception as part of the nation’s air defense network. The unit was stationed at various locations, including McChord Air Force Base in Washington and Fort Lawton Air Force Station, playing a crucial role in monitoring North American airspace for potential threats. The 635th AC&W Squadron was inactivated in 1963 as advancements in radar technology and shifts in defense strategies led to the reorganization of Air Defense Command assets.
